Applying crossover frequencies to passive speakers using a receiver w/o crossover settings

post #1 of 2
Thread Starter 
I have some questions about utilizing crossover frequencies for a 2.1 setup. I have a stereo receiver with no digital crossover setting (Harmon Kardon HK 3485.) I've connected my subwoofer to the receiver via the 'LFE out' using a single coaxial cable, and the speakers to the receiver using speaker wire of course. The subwoofer has it's own internal crossover dial.

With this setup, am I correct to assume that:

1. Regardless of where the crossover is set on the subwoofer, the bookshelves are constantly getting the full range audio signal from the receiver, since the crossover is set on the sub and not the receiver. Thus, i'm experiencing "cascading" frequencies as my subwoofer's crossover is set at 100Hz and my speakers go down to ~55Hz. Is this right?

2. If so, would the ideal method be to run speaker wire from the receiver's outputs to the subwoofer's left/right inputs, and speaker wire from the subwoofer's left/right outputs to the bookshelves? Would this send only frequencies above the subwoofer's crossover setting to my speakers?

I know a simple solution would be to set the sub's crossover lower to match the bookshelves' estimated lowest frequency, but i'd rather have the sub take care of everything below 100 or 80Hz.

Connect the pre out of your receiver to the L/R input of the sub, connect the L/R output of the sub to the Main in of the receiver. You will have to remove the jumper. Then you can set the crossover on the sub

#2 would be your best bet if your sub has speaker level inputs and doesn't have L/R inputs/ outputs.
